ADJUSTABLE BRACKET.

' No. 863,068. Specification of Letters Patent. Patented Aug. 13, 1907.

Application filed March 4, 1907. Serial No. 360,451.

To all whom it may concrrn:

Be it known that we, JOHN T. Hprr and GEORGE WILLIAM Hrrr, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Adjustable Bracket, of which the following is a specification.

This invention relates to a bracket and its support, by means of which shelves, etc., upheld by said bracket may be quickly changed in height without the necessity of removing any fastening devices, such as nails, screws, bolts and the like.

The object of the invention is to provide a bracket with attaching lugs disposed in pairs on opposite sides of the center plate, by means of which lugs, the bracket The spaces between the lugs 13 and 14 is such that when attached to the wall plate, the. lugs 4 thereon snugly fit the spaces and the under surface of the lugs 14.

Each group of lugs 4 on the wall plate comprises four lugs, each of which lugs project upwardly and outwardly from the face of the wall plate 3, their upper surfaces forming with the wall plate 3 an angle similar to that formed by the lower faces of the lugs 13, 14 on the bracket with the perpendicular flanges 10, and'are similarly spaced, so that when the bracket is applied to the wall plate, the lugs 13, 14 on the bracket will engage the lugs on the wall plate and securely hold the bracket against accidental detachment. The lugs of the group 4 are divided into two sets or lesser groups 15, 16, on

may be hung from similarly disposed lugs projecting in opposite sides of the longitudinal center of the wall groups froina-wall pate of indefinite length. The posiplate, the space between said sets 15, 16, being great tion of the bracket is readily changed by disconnecting enough, only to permit the rib 12 on the bracket to it from one group of lugs and attaching it to another.

These and other objects not specifically recited will be described in detail hereinafter and pointed out in the claims.

In the accompanying drawings: Figure 1 is a side elevation representing two brackets attached to the wall plate and a shelf supported by each bracket. Fig. 2 is a face view of the wall plate and asingle bracket supported thereon. Fig. 3 is a perspective view of a. bracket and a portion of the wall plate, separated.

Similar numerals indicate corresponding parts in all the [i gures.

Attached to a wall 1 or other suitable support by means of screws 2, is a wall plate 3, from the face of which project groups of lugs i, on each of which groups may be supported a bracket 5. The bracket 5 comprises a thin body plate 6, on the upper edge of which is a flange 7 extending on each side of the body plate and to which a shelf 8 is secured by screws or other means. Depending from the flange 7 perpendicularly thereto are two flanges 10, one on each side of the bracket, said flanges 10 extending nearly to the bottom of the bracket, their lower ends curving inwardly as shown at 11, Figs. 2 and 3. Extending rearwardly from the flanges 10 is a rib 12 forming a continuation of the body plate 6, the rear edge of the rib 12 being parallel to l the flanges 10 and perpendicular to the flange 7. The rib 12 is by preference made a little thicker than the body plate. Integral with the rib 12 are two lugs 13 at the top of the bracket just under the flange 7, and two other lugs 14: a short distance below the lugs 13, a lug 13 and 14 being placed on each side of the rib 12 opposite each other. The lugs 13 and 14 project laterally from the rib 12 to the edges of the flanges 10 on each side and enter therein. The rib 12 is preferably made of such length that it will pass at its lower end between the sets or smaller groups of lugs 15, 16, in the larger group '4 immediately below the one with which the ribs 13, 14 of the bracket are engaged. From this construction it will be clearly understood that the bracket is held rigidly in place on the wall plate and prevented from swinging or making other lateral movements by reason of the position of the rib 12 between the group sets 15, 1G. I

Having thus described the invention what is claimed 1. In an adjustable bracket, the combination plate having a vertical flange on tical rib extending rearwardly from' said flanges, a top flange at right angles to said vertical flanges, and a plurality of rearwardly projecting lugs integral with said vertical flanges and vertical rib and extending to the rear edge of said rib, the under faces of said lugs being inclined and in parallel planes, of a wall plate having a plurality of forwardly projecting lugs arranged in groups equal in number to the lugs on said bracket and having their faces similarly inclined, each group of lugs being divided into two sets between which the rib extends in vertical direction.

2. In an adjustable bracket, the combination with the body plate having a vertical flange on each side thereof, a vertical rib extending rearwardly of said flanges and a pair of lugs on each side of said vertical rib and integral there withand with the flange on its I'QSPGCtlX'G sides, the rear faces of said lugs being flush with the rear edge of the vertical rib and their lower edges lying in parallel planes, of a wall plate having a plurality of forwardly projecting lugs arranged in groups of four separated laterally into pairs between which the vertical rib extends, the lower end of said rib entering between the lugs of the group below that supporting said bracket.

In testimony that we claim the foregoing as our own, we have hereto afiixed our signatures in the presence of two with a body are placed in the angular spaces formed by the junction Witnesses JOHY T HUFF L i of the 11b 12 with the flanges 10. The rear ends of the GEORGE WILLIAM lugs 13 and 14 are in the plane of the rear edge of the rib I Witnesses 12 and then under faces are inclined downwardly and (3, OGDEN, rearwardly in parallel planes as shown in the drawings.
